(But it’s also heavily on sale right now, for $15 - https://store.steampowered.com/app/526870/Satisfactory/)
Personally, I don’t mind at all. For one I bought it at $30, but also I have 2,000 hours logged. Per hour that’s a cost of $0.02 per hour (at the new price) if I had bought it at $40. I’m all for calling out studios like ubisoft for being greedy, but coffee stain has done a very fair job with Satisfactory IMO, and they very well deserve $10 more for the game.
That being said, go pick it up now for $15
Inflation is not the only factor in the pricing on products. Otherwise a potato would cost 1000x what it does.
Even then, all the things you mention are media that was already produced, and the only cost associated to them now is licensing and distribution. Satisfactory is still in production, which costs orders of magnitude more.
The costs of updates and bug fixes, ie maintenance, aren’t equivalent to building the game from the ground up.
